Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, brake cleaner.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Inspect and Replace Wheel Speed Sensors

Locate the ABS Wheel Speed Sensors: Identify the location of each wheel speed sensor at all four wheels.
Remove the Wheel: Use a socket set to loosen and remove the lug nuts. Lift the vehicle using a jack and secure it with jack stands.
Disconnect the Sensor Connector: Carefully unplug the sensor wiring harness from the sensor.
Remove the Sensor: Unscrew and remove the sensor from its mount.
Inspect and Clean: Check for dirt or corrosion. Clean the mounting area with brake cleaner.
Install New Sensor: Position the new sensor in place, secure it with screws, and reconnect the wiring harness.
Reinstall the Wheel: Place the wheel back on, hand-tighten the lug nuts, lower the vehicle, and torque the lug nuts to the manufacturer’s specification.

3. Check and Replace ABS Fuse

Locate the Fuse Box: Refer to the owner’s manual to find the ABS fuse in the fuse box.
Remove the Fuse: Use a fuse puller or pliers to carefully remove the fuse.
Inspect the Fuse: Check if the fuse is blown (the metal strip inside the fuse will be broken).
Replace the Fuse: If blown, replace it with a new fuse of the same amperage.
Reconnect Battery: Once the fuse is replaced, reconnect the battery.

4. Clear Error Codes

Reconnect OBD-II Scanner: Reconnect the scanner to the vehicle’s OBD-II port.
Clear Codes: Follow the scanner instructions to clear any ABS-related error codes.
Test Drive: Drive the vehicle to confirm that the ABS light does not return.
